Puzzle Vault: 20 Brain Games

Twenty puzzle games in one app. Sudoku, Minesweeper, Solitaire, Nonogram, Klotski and sixteen more, each with four difficulty tiers and thousands of levels.
NO LIVES. NO TIMERS. NO ENERGY BAR.
Play for two minutes or two hours. There is no five-lives system, no countdown while you wait to play again, and no clock pressuring your next move. Puzzle Vault is built for people who want to think, not hurry.
EVERY PUZZLE PLAYS FAIR
Most puzzle apps generate levels at random and hope. These do not.
Minesweeper boards are checked before you ever see them, so every one can be finished by pure deduction. You will never lose to a coin flip at the end.
Bridges, Sudoku, Recipedoku and Nonogram levels are all verified to have exactly one solution, reachable by logic alone.
Klotski positions come from a full search of the board, so every level is solvable and the app knows the shortest possible route.
FOUR TIERS PER GAME
Recruit, Pro, Elite and Grandmaster. Each tier keeps its own progress, so you can be on level 3 of Grandmaster Sudoku and level 40 of Recruit at the same time. Every game remembers exactly where you stopped, mid-level, and picks up there when you return.

BUILT TO BE PLAYED, NOT GRINDED
Unlimited undo in almost every game, so exploring a line costs you nothing. Levels are generated fresh rather than repeated, so the games do not run out. A Continue row on the home screen puts whatever you were last playing one tap away.
Every game includes a How to Play guide with the rules and real strategy tips, not just a list of controls.
GOOD FOR
Long journeys, waiting rooms, winding down before bed, or any time you want something to occupy your brain without a timer counting down at you. Suitable for all ages.
Puzzle Vault is free to play and supported by ads. An occasional full-screen ad appears between levels, and some games offer an optional ad in exchange for a hint or an extra try. You never have to watch one to keep playing.
